使用HTMLAgilityPack解析javascript HTML [英] Parsing javascript HTML using HTMLAgilityPack
问题描述
我尝试使用HTML Agility Pack解析以下HTML.
I have the following HTML that I'm trying to parse using the HTML Agility Pack.
这是HTML代码段:
<body id="station_page" class="">
...
<div>....</div>
<script type="text/javascript">
if (Blablabla == undefined) { var Blablabla = {}; }
Blablabla .Data1= "I want this data";
Blablabla .BlablablaData =
{ "Data2":"I want this data",
"Blablabla":"",
"Blablabla":0 }
{ "Blablabla":123,
"Data3":"I want this data",
"Blablabla":123}
Blablabla .Data4= I want this data;
</script>...
我正在尝试获取这4个数据变量(Data1，Data2，Data3，Data4).首先，我试图找到javascript:
I'm tring to get those 4 data variable (Data1,Data2,Data3,Data4). first, I tried to found the javascript:
doc.DocumentNode.SelectSingleNode("//script[@type='text/javascript']").InnerHtml
如何检查它是否真的是正确的javascript?找到相关的javascript之后，如何获取这4个数据变量(Data1，Data2，Data3，Data4)?
How can I check if it's really the right javascript? After finding the relevant javascript how can I get those 4 data variable (Data1,Data2,Data3,Data4)?
推荐答案
您无法使用HTML Agility Pack解析javascript，它仅支持HTML解析.您可以使用XPATH来获得所需的脚本，如下所示:
You can't parse javascript with HTML Agility Pack, it only supports HTML parsing. You can get to the script you need with an XPATH like this:
doc.DocumentNode.SelectSingleNode("//script[contains(text(), 'Blablabla')]").InnerHtml
但是您需要使用另一种方法(正则表达式，js语法等)来解析javascript
But you'll need to parse the javascript with another method (regex, js grammar, etc.)
